DETACHABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 627,578, dated June 27,1899. Application filed June 3,1898. Serial No. 682,468. (No model.)

To all whom it may concern:

Be it known that I, JOHN R. FARRELL, a citizen of the UnitedStates,residing at Boston, in the county of Suffolk and State ofMassac'husetts, have invented a new and useful Improvement in DetachableButtons,of which the followingisafull, clear, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification, in explaining its nature.

The invention relates to a detachable button having as an attachingdevice a metal hook, which is hinged at one end to one edge of thebutton-shank in a manner topermit its point or free end to be movabletoward and from the corner of the other edge on an arc of a circle, anda locking bar or device which is pivoted to the shank of the button uponthe edge opposite that to which the hook'is pivoted, and whichlocking-bar has a lateral arm or extension, preferably curved, which isadapted to be moved back of and against the shank of the hook when inits closed position, and to lock the hook in its closed position and tobe held in said locking position by its own resiliency, the said lockingbar or device being upon the outside of the button-shank and beingsituated where it may be readily operated either to lock the hook in itsclosed position or to permit of the opening of the same preparatory todisengaging the hook from the garment or material to which the button isbeing secured.

In the drawings, Figure 1 is a View in perspective of the detachablebutton inverted and with the hook in its open 'or engaging position.Fig. 2 is a view in elevation of a button, representing the hook asengaging the material of a garment and as fastened in engaging position.Fig. 3 is a cross-section upon the dotted line 3 3 of Fig. 2, and Fig. 4is a cross-section upon the dotted line 4 4 of Fig. 2.

Referring to the drawings, Arepresents the button. From its back a thereextends a shank a, which may be of any desired shape. The onerepresented is rectangular in crosssection and has the flat outer end aB is a curved fastening-hook. It is pivoted at b in a recess in one edgeof the shank and near its inner end, and it is shaped substantially asrepresented in Fig. 1, so that when fully opened its point b is in theengaging position therein shown, and when closed the hook assumes theposition represented in Fig. 2that is, it is in line with the shank, andthe point Z) then closes into a small hole 61, 31] its end. The shankmay be made in any desired way, and the hook may be pivoted to it in anydesired manner. I have representedas one way the prick-punching of thesubstance of the shank into an eye of the hook; but while this is acheap and simple method of pivoting the hook to the shank of the buttonI do not limit myself to such manner of attachment.

O is the hook-lock. It is pivoted at c to the edge of the shank oppositethat to which the hook is pivoted, and it extends across the shank andhas a curved outer end 0', which is adapted to be moved upon the outerside of the hook near its pivotal point when the hook is in its closedposition. (See Figs. 2 and 3.) It then acts to lock the hook to theshank and prevent any movement thereof, so that the hook is convertedinto a stationary metal loop. The look is held in closed or lockedposition by the slight projection a on the edge of the shank, over whichthe part c of the lock is slightly strained to the receiving-notch abeyond, and the projection a upon the other side of the notch preventsthe further movement of the hook-lock. This constitutes what may betermed a hooklock retainer. The resiliency of the section 0 of thehook-lock holds it in the notch a against accidental displacement. Torelease the hook, it is simply necessary to move backward the hook-lockto its original or innermost position. This hook-lock,it will be seen,is at all times readily accessible both for the purpose of closing orlooking the hook and for the purpose of releasing it. In use the hook ismoved to the position represented in Fig. 1, when its point may beeasily passed through the material of the'garment or thing to which itis to be attached, especially if the said material is folded to receiveit. The movement of the hook-look to locking position will then causethe hook to be turned to assume the form of a loop at the end of theshank, and the engagement of the lock with the notch serves to lock thehook as a stationary engaging and fastening loop. To remove the button,the hook-lock is moved backward to its original position, and the hookis then free to be withdrawn from the material.

It will be seen that the hook-lock when released occupies the positionwith respect to the button-hook shown in Fig. 1, when it is very nearlyin line with the pivot of the button-hook, and that its locking positionis shown in Fig. 2, which represents its long end as moved from saidpivotal point to a looking position at one side of the pivotal point.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States-- 1. A detachable button having ahook B pivoted at one end to the button, to be movable in respect to itsback as shown and described, and a hook-lock pivoted to the back of thebutton at a point diametrically opposite that at which the hook issecured, and having at its free end a lateral extension which extendsacross the button and around the plane of the said hook, and is adaptedto be swung against the rear of said hook and past its pivotal point, asset forth.

2. A button having a shank a, a hook B pivoted to one edge of said shankand alooking-bar C pivoted near the opposite edge of said shank, andhaving a lateral locking extension c passing around the plane of saidhook and adapted to be swung against its base, and a hook-lock retainer.located to engage said hook-lock,when in its locking position, withrelation to said hook, as set forth.

3. The detachable button havingthe shank a, the hook B, a hook-lock Cpivoted to the shank and adapted to engage the hook as specified, and ahook-lock retaineincomprising the notch 60' in the edge of the shank,and the slight projections a, a on each side of the'notch.

JOHN R. FARRELL.
